3 Product description
The leak detector consists of a control unit, a probe and a container
for leak detection fluid (black LAG container).
The control unit and the probe are connected by means of a two-wire
signal cable with a maximum length of 50 m.
The probe is plugged into the top of the black LAG container. In the
case of a leak in the interstitial space, the leak detection fluid level in
the black LAG container falls. The electrode rods of the probe are no
longer submerged in the leak detection fluid. The control unit detects
the change in resistance and generates an alarm.

3.1 Application area
Tanks
Only the following tanks are approved: double-walled containers
(tanks) which are operated under atmospheric conditions and which
comply with the standards DIN 6616 type A, DIN 6623-2, DIN 6624-
2, EN 12285-2 (type D) and EN 12285-1 (type D) or which have an
approval that the interstitial space is suitable for connection of a liq-
uid-based leak detection system.
The interstitial space volume of the system must not exceed 1 m³.
Stored liquids
Only the following liquids are approved:
•Water-polluting liquids.
•Flammable liquids with a flash point of > or ≤55 °C.
Approved storage media
If the containers (tanks) are operated under atmospheric conditions
and depending on the design of the containers (tanks), water-pollut-
ing liquids with the following densities may be stored in the contain-
ers (tanks):
•Tanks as per DIN 6616 type A, DIN 6623-2 and DIN 6624-2
≤2.5 m Ø permissible density ≤1.90 g/cm³
≤2.9 m Ø permissible density ≤1.85 g/cm³
CAUTION
Danger of reaction of leak detection fluid and stored liquid if un-
suitable leak detection fluid is used.

The leak detection fluid and the stored liquid may not react.
Proven compatibility is required.

Observe the information on the intended use in chapter 2.1,
page 5.
3.2 Function
The LAG-14 ER leak detector monitors the interstitial space of dou-
ble-walled tanks filled with leak detection fluid. In the case of a leak
in the inner or outer wall of the container (tank), above or below the
levels of the stored liquid or the ground water, the leak detection fluid
escapes. This causes the level of the leak detection fluid to fall. The
electrode rods of the probe are no longer submerged in the leak de-
tection fluid. The control unit detects the change in resistance, gener-
ates visual and audible alarms and actuates the output relay.

Product description
LAG-14 ER 11
Probe
The black LAG container is installed above the interstitial space. The
bottom side of the black LAG container is connected to the top of the
interstitial space via a hose. This way, the black LAG container is the
top part of the interstitial space. The interstitial space is filled with
leak detection fluid to the middle of the black LAG container. The
probe is installed from the top of the black LAG container so that the
electrode tips are covered by the leak detection fluid. Both electrodes
are connected to the control unit by a two-wire cable.
Control unit
The control unit continuously monitors the electrical resistance be-
tween the two electrodes of the probe. The green pilot lamp lights up
when the device is ready for operation. If the probe resistance is less
than 5 kΩ, there is no alarm condition: The red alarm lamp is off, the
relay is:
•De-energised (in the operating mode Eco)
•Energised (in the operating mode FailSafe)
If the resistance is greater than 5 kΩ, an alarm condition, i.e. a leak
has been detected by the control unit: The red alarm lamp and the
audible alarm are on and the relay is:
•Energised (in the operating mode Eco)
•De-energised (in the operating mode FailSafe)
The audible alarm can be muted with the "Acknowledge" button in
the case of an alarm.
No alarm is triggered in case of a power outage. When mains voltage
is restored, the product immediately resumes operation. If a leak has
occurred in the meantime, this is signalled.
The green pilot lamp lights up as soon as the leak detector is sup-
plied with mains voltage. The Test button allows you to simulate an
alarm condition in order to perform a function test.

Product description

3.3 Operating modes
Eco:
The LAG-14 ER leak detector is equipped with an output relay to
transmit the alarm signal to additional external devices. If no error
condition is present, the relay is de-energised; in case of an alarm,
the relay is energised.
FailSafe:
The LAG-14 ER leak detector is equipped with an output relay to
transmit the alarm signal to additional external devices. If no error
condition is present, the relay is -energised; in case of an alarm, the
relay is de-energised.
The leak detector LAG-14 ER can be operated with or without addi-
tional external devices. External devices include units for audible and
visual alarm signal or remote alarm devices, building control sys-
tems, etc.

6 Mounting and commissioning
6.1 Calculation fundamentals
LAG-14 ER at underground container (tank)
The effective capacity of the black LAG container is limited by the liq-
uid level screw in the centre of the container; it amounts to 4.5 litres.
For underground containers (tanks), 1 litre of leak detection fluid is
required in the black LAG container per 100 litres of interstitial space
volume.
The black LAG container is sufficient for 450 litres of interstitial space
volume. This corresponds to containers (tanks) with a storage vol-
ume of up to 60,000 litres.
Together with additional containers with an effective capacity of 4.5
litres each, the LAG14 ER leak detector can also be used for tanks
with a greater interstitial space volume.
The additional containers are connected to each other and to the
black LAG container by means of EPDM hoses.

In the case of new installations, the interstitial space volume of the
system must not exceed 1000 l.
LAG-14 ER at aboveground container (tank)
For aboveground containers (tanks), 1 litre of leak detection fluid is
required in the black LAG container per 35 litres of interstitial space
volume.
One black LAG container is sufficient for 157.5 litres of interstitial
space volume. This corresponds to containers (tanks) with a storage
volume of up to 20,000 litres.
Together with additional containers with an effective capacity of
4.5 litres each, the LAG-14 ER leak detector can also be used for
tanks with a greater interstitial space volume.
The additional containers are connected to each other and to the
black LAG container by means of EPDM hoses.

6.2 Installing the container for the leak detection fluid
Verify the volume of leak detection fluid required (check the
nameplate at the tank (container)) and determine the number of
required black LAG containers as described in chapter 6.1,
page 17).
The black LAG container can be mounted directly next to the control
unit or in the vicinity of the container (tank) to be monitored in haz-
ardous areas (Ex) zone 1 and zone 2 (e.g. in the manhole).
When installing the LAG container in the hazardous area (Ex),
in the manhole or outdoors, make sure neither surface water no
rain nor dirt nor airborne sand can get into the container or into
the cable junction box.
Mount the black LAG container high enough above the intersti-
tial space for the static pressure of the leak detection fluid to be
sufficient at all points of the interstitial space to cause the leak
detection fluid to escape and the leak detection fluid level in the
black LAG container to fall in the case of a leak so that an alarm
can be triggered.
The minimum distance between the tank top and the bottom of
the black LAG container primarily depends on the density of the
stored medium and, in the case of underground tanks, on the
possible level of the ground water or backflow above the tank
top. Mount the black LAG container at least 30 cm above the
tank top.
If the test pressure for the interstitial space of the tank is 0.6 bar,
the black LAG containers (with reference to the liquid level
screw) may be no higher than 5.5 m above the bottom of the
tank.
